METHOD OF MAKNGr EMBOSSED DESIGNS.

Application filed August 2, i928. Serial No. 296,969,

The main objects of, this inventionare to provide an improved method ofproducing embossed lettering or'designs; and 'to proride an improvedmethod of applying a fusible material such as sealing wax toa'suppcrting Janel for aroducin an embossed advertisino` card or othersign which is decorative.

An illustrative' .embodiment of certain means for carrying out thisimproved method is shown in the accompanying drawing, wherein Figure lis a perspective of four matrix blocks supported on a base panel forreceiving the fused sealing wax from an applicator.

Fig. 2 is an enlarged transverse section taken on the line 2-2 of Fig. land showing the sealing wax after it has congealed.

Fig. 3 is an enlarged detail in perspective showing a portion of theembossed matter.

Embossed advertising display cardsand other signs have-been madecommonly with sealing wax applied to a receiving sheet or card. VVaxesof different colors have been used for the letters or other designs.

Heretofore, the process of making such embossed designs has beenperformed entirely with `a hand operated writing instrument,

Y from which the melted wax iiowed directly onto the receiving sheetwithout the use of a matrix. The'instrument was used somewhat like afountain pen. In view of the fact that it was all free hand work, theprior method was slow and expensive, required skilled oplerators andartists and no two pieces of work were identical. The prior method was,therefore, impractical for quantity production.

My improved method of producing embossed designs includes the use of amatrix adapted to be placed on the base panel for receiving the meltedwax. rihe matrix is made of a material, preferably metal, to whichsealing wax will not adhere and the back thereof is open andunrestricted so that thetop surface of the sealing wax is permitted toform a natural convex meniscus, which clearly distinguishes the designfrom one having molded characters.

When liquid comes in contact with a solid which is moistened by it, theliquid is raised upwards against the sides of the solid and its surface,instead of being horizontal, is slightly concave, forming a concavemeniscus, if, on the contrary, the solid is one which is not moistenedby the liquid, the liquid is depressed against the sides of the solidand assumes a convex shape, forming a convex meniscus.

` lVhen melted sealing wax comes in contact with metal and the surfaceof the liquid is not cc-nned by a top or cover,`it forms a naturalconvex meniscus.

The improved matrix may comprise a single block for each design or aplurality of separate blocks each of which contains a portion of thedesign as, for instance, a single letter.

ln the form shown in the drawings, a plurality of separate matrix blocksl are supported on a base 2 for receiving a fused medium, such assealing wax from an applicator 3 or other suitable device.

The blocks l are made of metal or any other suitable material to whichthe fusible medium will not adhere and the base 2 may be made ofV paper,card-board, wood or other material to which wax will adhere.

The letters or other characters extend through the block, so that theback of each block is open and unrestricted. Certain let ters, such asR, require bridge portions 4. to support an intermediate part, such-asthe part 5. Sufficient draft is provided in each matrix to permit theblock to be readily withdrawn after the wax has set.

The applicator 3 may be of any desired construction. in the form shown,it includes a magazine 6 adapted to contain the sealing wax, which isejected through a nozzle 7 controlled by a valve mechanism 8. Anelectric heater 9 is provided for heating the wax. rlhe magazine issupported on an arm 10 pivoted to a link 11, which is rotatably mountedon a standard l2, whereby the nozzle 7 may be manually shifted to anydesired position over the blocks l.

In carrying out this improved method, the base 2 is placed in ahorizontal position on a table or other support, on which the standardl2 is mounted. rihe matrix blocks l are then placed in the desiredposition on the base 2. The operator then moves the applicator nozzleover each letter and opens the valve mechanism thereby permitting themelted wax to flow through the open back of each natrix to form theletters 13.

YWhen the sealing wax comes in contact with the metal walls of thematrix, the top surface of the wax forms a natural convex meniscus 14,which gives the finished design an appearance which is exceedinglyattractive. Y Aft-ei' the Wax has hardened, the nmt-i'ix blocks larereino-ved foi' further use.

It- W'ill be understood that details o'i' the construction shown may bealtered o1 omitted and steps in the method varied without de gesl withconvex meniscus, and then Separat- 2. The method of making embosseddesigns which consists 1n providing a base to which sealing Wax -willadhere, placing upon the base a matrix having an unrestricted openlrmoleundlefned iby Walls to which said sealing Wax will notiadheie,intioducng fused seuling Wax through the back of said mat-fix,

allowing said Wax to Cool .so as to oongeal with a convex meniscus, andthen separating seid matrix and hase.
